As a certified bike mechanic and long time user of chain cleaning products, I consider this the best design out there. No chain cleaner is completely mess free, but this one comes close. (That's was used newspaper is for!) Please use a biodegradable degreaser.

Some have mentioned incompatibility between degreasers and lubes, I have not had an issue with that.

Good-grade plastic housing is not as cheap as it looks in the picture. You get a thorough cleaning without running through a wad of cloth rags. Is practical to clean several chains at one sitting with this device. It still leaves small drips and spray on the floor, however it should be easy for most people to operate. A clean drive train is a quiet drive train.

Don't loan it to a friend...You won't get it back. One ride in the Seattle rain can fill the chain with grit and affect shifting. I use this scrubber a lot. I keep a gallon of simple green on the shelf next to it. I run it through the gears to clean the rear cassette at the same time. The Park tool model is pretty cheesy in comparison and harder to use. I don't bother using the handle, it's easier for me to simply hold the scrubber with my hand around it.

Does the job very well and at the price is a great deal. It was a bit difficult at first to use and it does leak a little, but all chain cleaners tend to be a bit messy with two open ends. The chain ended up very clean and you can see how dirty your chain is once you empty the chain cleaner chamber.

At first it was difficult to use, the chain kept coming off the front sprocket. Then got the hang of keeping it pushed up against the rear wheel to keep aligned, and putting bike in higher gear on rear wheel. There is still major drippage as chain emerges from unit so use a rag on floor under device and backpedal s-l-o-w-l-y.

As my headline says Wow! I only thought my chain was clean when I used spray degreaser and Finish Line Grunge brush. This thing is incredible. A bit messy (at least for me) but it removed crud I didn't even know was in the chain. Really great design and comfortable to use. Highly recommended. I will do it outside next time in the grass with biodgradable degreaseer becasue it got messy for me. Maybe I was rotating the chain too fast. Do your chain a favor and Get One

I used a Park Tool chain cleaner for over 12 years before it broke. Each time I used it I had to be ready to get full of chain cleaner and water. It was very messy. This chain cleaner hasn't leaked once yet and it has been easier to hold. It cleans just as well as the Park Tool model but for my money it is cleaner and easier. I have used it now over 15 times on my chaing and I think it is the best chain cleaner I have used.

Just drop some chain degreaser in, spin the chain, and wala...clean chain. I thought it worked well. It was much better then the mess I made without it. Still, best used outside or in the garage. You're still likely to get something dirty.

This chain cleaner worked very well. It does a great job on the chain but is not designed to clean the sprockets, gears, etc. I also purchased the Finish Line Grunge Brush(item #FL-GB) which is capable of cleaning the chain and other components. They were a good purchase together for the price but I'd go with the grunge brush if I had to buy just one.
